Simple program to print the environment variable names in order (apparently there is an order)

print_env.go

package main

// docker run -it --rm -v `pwd`:/src -w /src golang go build print_env.go

import (
        "fmt"
        "os"
        "strings"
)

func main() {
  environment := os.Environ()

  for i, env := range environment {
    e := strings.SplitN(env, "=", 2)
    fmt.Printf("% 3d) %s\n", i, e[0])
  }
}
